the function $y = f(x)$ is graphed below. what is the average rate of change of the function $f(x)$ on the interval $-3leq xleq2$?

the function $y = f(x)$ is graphed below. what is the average rate of change of the function $f(x)$ on the interval $-3leq xleq2$?

Answer

Explanation:

Step1: Recall the average - rate - of - change formula

The average rate of change of a function $y = f(x)$ on the interval $[a,b]$ is given by $\frac{f(b)-f(a)}{b - a}$. Here, $a=-3$ and $b = 2$.

Step2: Find $f(-3)$ and $f(2)$ from the graph

From the graph, when $x=-3$, $y=f(-3)= - 8$; when $x = 2$, $y=f(2)=8$.

Step3: Calculate the average rate of change

Substitute $f(-3)=-8$, $f(2)=8$, $a=-3$, and $b = 2$ into the formula $\frac{f(b)-f(a)}{b - a}$. We get $\frac{f(2)-f(-3)}{2-(-3)}=\frac{8-(-8)}{2 + 3}=\frac{8 + 8}{5}=\frac{16}{5}=3.2$.

Answer:

$3.2$
